Dear Mr. President …

Eli Saslow (thanks, Wright): The black binder arrived at the White House residence just before 8 p.m., and President Obama took it upstairs to begin his nightly reading. The briefing book was dated Jan. 8, 2010, but it looked like the same package delivered every night, with printouts of speeches, policy recommendations and scheduling notes. Near the back was a purple folder, which Obama often flips to first.

"MEMORANDUM TO THE PRESIDENT," read a sheet clipped to the folder. "Per your request, we have attached 10 pieces of unvetted correspondence addressed to you."
